The general object ofmy present invention is the provision of a methodof pro-' ducing relief maps, and this in such manner that the mapsproduced are accurate in character and are calculated to give good ideasat a glance of the terrains mapped.

The invention consists in a peculiar and advantageous relief mapproducingprocess. With the foregoing in mind the invention will be fullyunderstood from the following description and claims when considered inconnection with the accompanying drawings, forming part of thespecification, in which:-

Figure 1 is a plan view illustrative of the initial steps ofmy novelprocess. V Figure 2 is a vertical section taken in the plane indicatedby the line 22 of Figure 1, with the embossing element in elevation andalso shown by dotted lines in different positions.

Figure 8 is a plan view illustrative of the second step of my novelprocess.

Figure 4 is a section taken in the plane indicated bythe line 44 ofFigure 3, dotted lines being employed to represent the embossing elementin different positions.

Figure 5 is a vertical section illustrative of my novel relief map asthe same appears when completed, said section being taken in the planeindicated by the line 5-5 of Figure 6.

Figure 6 is a top plan view of said relief map.

Figure 7 is a side elevation of the relief map.

Figure 8 is a fragmentary section illustrative of the manner in which anarea within the limits of a contour line is embossed to thepredetermined depth or scale.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

I show in Figures 2 which is disposed a base 4 of sand or other approvedyielding material.

In carrying out my process I position a sheet 2 of ductile metal on thecontainer 3 and over the said base 4, the sheet being ar- 50 ranged facedownward as will be manifest and 4 a container 3 in from Figures 2 and4. The sheet 2 alluded to is characterized by the representation on theback side thereof of one or more contours, and in the illustratedexample of a plurality of contours the outer line of the outer contouris designated by 5 in Figures 1 and 3, and the outer line of the nextinner contour is designated by 6 in Figure 3. It 'will also be notedthat legends are provided on the back side of the sheet, Figure 8,indicative of the heights to which the contours are to be embossed; thelegend 100 by way of example being placed adjacent the outer line 5 ofthe outer contour, and the legend '200 being placed, by Way of example,adjacent to the outer line 6 of next highest embossment.

At 1 in Figures 1 and 2 is the handle of an embossing element 7, saidembossing element being illustrated by full and dotted lines in Figure2, by full lines in Figure 1, and thehead of said element beingrepresented by dotted lines in various positions in Figure 4. Thisapplication is filed in the place and stead of my contemporaryapplication Serial N 0. 544,933, and within the purview of myinvention'the embossing element may be of any approved character as, forexample, the embossing element comprised in the apparatus constitutingthe subject of my application filed June 12, 1931, Serial No. 543,926,.patented May 31, 1932, N 0. 1,860,729.

It will be understood from the foregoing that when first placed over theyielding base 4 the sheet 2 is in a straight and flat state bearing thecontour representation and by preference the legends hereinbeforereferred With the sheet 2 positioned as stated and secured in saidposition, if necessary, my process is as follows First by blows of theembossing element, the metal is displaced within the line 5 andthroughout the area of the contour to the de th indicated by 7a; inFigures 2 and 4.

econd. A portion of the initially displaced metal is similarlydisplaced, within the line 6, to the greater depth indicated by 800 inFigure 4.

The steps or similar steps are repeated until the sheet is reduced tothe shape shown in Figures 5, 6 and 7.

The corners between the several layers of the sheet of metal aredesignated by 5a, 6a, 1O, 11, and 12 in Figures 5 to 8, inclusive, andmanifestly said corners constitute contours.

The essence of my invention lies in the expeditious production of arelief map that is at once accurate and calculated to impart at a glancean adequate understanding of the character of the terrain mapped.

Manifestly the expedition with which an accurate relief may may beproduced in accordance with my invention will be materially advantageousin war time when armies are in motion and unless a map can be quicklyproduced its production is likely to be too late.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is 2-- 1. A relief map producing process comprisingrepresenting on one side of a sheet of ductile metal a series ofcontours, and embossing the series of contours one after the other untilthe highest elevation is reached to proportionately represent hills orhill portions of different heights in relief at the opposite side of thesheet; the lowest elevation being embossed throughout the area of andwithin the outermost contour, and the next highest elevation beingembossed throughout the area of and within the 'con-' tour next to theoutermost contour and by displacing part of the metal initially displaced for the representation of the lowest elevation.

2. A relief map producing process comprising representing on one side ofa sheet of ductile metal a series of contours and also placing on saidside adjacent the contours height-indicating legends, and embossing theseries of contours one after the other according to said legends toscale until the highest elevation is reached to proportionatelyrepresent hills or hill portions of different heights in relief at theopposite side of the sheet; the lowest elevation being embossedthroughout the area of and within the outermost contour, and the nexthighest elevation being embossed throughout the area of and withm thecontour next to the outermost contour and by displacing part of themetal initially displaced for the representation of the lowestelevation.

3. A relief map producing process com prising representing on one sideof a sheet of ductile metal a series of contours, and embossing theseries of contours one after the other until the highest elevation isreached to produce corners constituting contours and to proportionatelyrepresent hills or hill portions of difi'erent heights in relief at theopposite side of the sheet; the lowest elevation being embossedthroughout the area of and within the outermost contour, and the nexthighest elevation being embossed throughout the area of and within thecontour next to the outermost contour and by displacing part of themetal initially displaced for the representation of the lowestelevation.

4. A relief map producing process comprising representing on one side ofa sheet of ductile metal a series of contours and also placing on saidside adjacent the contours height indicating legends, and embossing theseries of contours one after the other according to said legends toscale until the highest elevation is reached to produce cornersconstituting contours and to proportionately represent hills or hillportions of different heights in relief at the opposite side of thesheet; the lowest elevation being embossed throughout the area of andwithin the outermost contour, and the next highest elevation beingembossed throughout the area of and within the contour next to theoutermost contour and by displacing part of the metal initiallydisplaced for the representation of the lowest elevation.

In testimony whereof I afiix my signature.
